ADJUSTABLE SPEED-GOVERNOR.

Specification of Letters Patent.

Patented Dec. 14, 1915.

' Application filed December 26, 1914. Serial No. 879,131.

To all whom it may concern.-

Beit known that I, HORACE E. WVOOLERY, a citizen of the United States, residing at Fairmont, in the county of Martin and State of Minnesota, have invented a new and useful Adjustable Speed-Governor, of which the following is a specification.

The present invention relates to improvements in an adjustable speed governor for engines, one ob ect of the invention, being the provision of an effective and compact structure, assembled with a shaft to operate a controlling valve at any desired speed, the present structure being especially adapted for use in connection with the valve and engine construction shown in my co-pending application Serial No. 1214, filed January 8, 1915.

A further object of the present invention is the provision of an adjustable speed governor mechanism, which is readily applled to explosion engines at a point adjacent to the fly wheel upon the crank or main shaft thereof and whereby the weight arms are disposed at a point near the axis of the shaft so that an exceedingly compact device is provided.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in. the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimedwithout departing from the spirit of the invention.

In the drawingsFigure 1 is a view in elevation of a portion of a fly wheel, with a section taken on line ll of Fig. 2. Fig. 2 is a longitudinal sectional view through the present governor mechanism. Fig. 3 1s a detail view showing the cam lug carried by the oscillatory ring and the various positions of the roller thereupon.

Referring to the drawings, the numeral 42 designates the crank shaft of an engine, which has fixed thereto, the fly wheel 48, while upon two of its diametrically opposite spokes are carried the projections or lugs 44. These projections are in the path of the rollers 45, j ournaled in the outstanding arms of two bell crank levers 46. These bell crank levers 46 have their elbows journaled at 47 to the lugs 48, and said lugs 48 are carried other arms 50 of the levers 46 project along the sleeve or shaft and are weighted and bifurcated or forked so that they loosely straddle the sleeve 49 and shaft 42, as clearly illustrated in Fig. 1, and thus the center of gravity is disposed nearthe axis of the fly wheel for purpose of compactness.

Disposed adjacent that end of the sleeve 49 remote from-the fly wheel 43 is the antifrictional bearing ring 52, which constitutes a thrust bearing between the end of the sleeve 49 and the sliding collar or ring 53. This sliding ring 53 is provided with a plurality of rollers 55, said ring 53 being slidably mounted upon the non-rotatable sleeve 54 mounted upon the shaft.

Mounted upon the sleeve54 for slight oscillation, is the ring 56, which as shown in Fig. 3, is provided with cam projections 57, there being one projection to each roller 55. Each roller 55 is arranged to abut the oblique face of its respective cam 57 and said ring 56 is adapted to be adjusted so that the rollers may assumenormally any of the dotted line positions, as shown in Fig. 3, accord ing to the speed at which it is desired to operate the engine. Connected to the ring 56 is an arm 58, which is offset and connected to the rod 59 to which the throttle (not shown) is connected.

It will thus be seen that when the sleeve 49 is moved to the right as viewed in Fig. 2, the ring 58 will be moved longitudinally and cause its rollers 55 to be moved into engagement with the inclined faces of the lugs 57 and as the rollers 55 only have a straight line movement, and as the ring 56 is permitted oscillatory movement, the engagement of the rollers upon the inclined faces of the lugs 57 will cause the ring 56 to be oscillated in the direction to move the rod 59 and subsequently close the throttle. The reverse movement will permit the ring 56 to assume its normal position.

It will thus be seen that as the speed of the fly wheel 43 increases, the weighted arms 50 will be thrown outwardly by centrifugal force so as to place the anti-frictional rollers 45 into engagement with the lugs 44 of the fly wheel, such points acting as fulcrums so that the sleeve 49 is moved to the right as viewed. in Fig. 2 to consequently move the rollers 55 against the cam lugs 57 to operate the throttle controlling rod or arm 59. -W-hatis claimed is: 7

1. A governor mechanism embodying a shaft having a Wheel thereon, a sleeve slid-..

against said wheel," and .the other arms eX- tendmg along the sleeve and being weighted.

2. A governor mechanism embodying a shafthaving a wheel thereon, a sleeve slidable upon the shaft, means operated by the movement of said sleeve upon the shaft for controlling a throttle valve, bell crank levers having their elbows pivoted to said sleeve, certain arms of said levers bearing against said wheel and the other arms extending along the sleeve and being bifurcated and weighted so asto straddle the sleeve.

3. A governor mechanism embodying a shaft having a wheel thereon, a sleeve mounted for longitudinal movement upon the shaft, bell crank levers having their elbows ivoted tothe sleeve and having certain arms earing against the wheel, while the other arms project along the sleeve and are Weighted, a ring disposed adjacent that end of the sleeve remote from the wheel to be operated by'th'e movement of said sleeve, and 'a'member adapted to be oscillated and having cam portions, said ring having portions to strike said-cam portions when the ring is moved by the sleeve.

4. A governor mechanism embodying a shaft havmg a wheel, a sleeve mounted for longitudinal movement upon theshaft, bell crank levers having their elbows pivoted to said sleeve and having certain arms bearing against said wheel, while the other arms pro.- j ect along the sleeve and are weighted, a nonrotatable sleeve upon the shaft, a ring,
